SPECIFICATION forming part of Letters Patent No. 556,069, dated March 10, 1896. Application filed January 15, 1895. Serial Ila-534,978. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, CLARK SINTZ, of Grand Rapids, Michigan, have invented certain new regulable quantities, depending ,upon the I speed at which it is desired to run such engine, and the valves which control the supply of air and gasoline to the mixing-chamber of the generator may be governed by the engine itself; and, further, the quantity of gas supplied may also be controlled by providing a suitable governor adapted to actuate the controlling-valve in the passage from the mixing-chamber of the generator to the explosion-chamber of the engine.

My invention consists, broadly stated, in the generator as a new apparatus, and more specifically in features of the construction and in the combination of parts thereof, as hereinafter described and particularly pointed out in the claims.

The accompanying drawing is an elevation, partly in section, through the reservoir, the valve-seats, mixing-chamber, and the outlet-passage and the valve-casing connected therewith.

Shortly stated, the generator comprises a reservoir for gasoline having a port or passage, a needle-valve for controlling the entrance to said port or passage, an air-chamber in communication with the external atmosphere, and a mixing chamber, in passing through which the gasoline and air are commingled, an outlet pipe or passage controlled by a check-valve having a prolongation of its Stem also controlling the gasoline-port, and a regulatingevalve interposed in the outlet pipe or passage for controlling the quantity of gas passing to the gas-consuming device. These parts,with a supply and an overiiow pipe and 5o the mechanism for operating the needle-valve land regulating-valve, constitute the mechanical features of the apparatus.

In the drawing, A represents the stem of a needle-valve which passes through the top plate of a reservoir L, having an internallythreaded boss extending upwardly from its `bottom plate and with which the valve-stem engages by mating threads. 'the port or passage through the bottom plate,

B represents and B/ an open port through the threaded boss. 6o Thervalve-port is preferably constructed on an angle of forty-five degrees, and the quantity of gasoline passing to the port may be accurately adjusted by the manipulation of the threaded stem. The exit end of the port B is controlled by a valve C, which is formed by the prolongation of the stem of check-valve D, whichis fitted into the upper wall of mixing-chamber F. An intermediate annular section', forming an air-chamber E', is perfo 7o rated, as at E, for the admission of air. A spring F normally holds the valve D to its seat, thus closing communication between the chamber El and the chamber F.

G represents a regulating-valve which is adapted to be projected to any extent desired into'the orifice of escape-pipe O, and said regulating-valve has a valve-stem H, to which is pivoted, at I, a lever K, pivoted at J to a supporting-bracket, and adapted to be controlled 8o manually or automatically by a governor applied thereto.

The reservoir may be filled in the first instance by the removal of the filling-plug L. A supply-pipe M communicates with the top of the reservoir, and through said pipe a supply of gasoline is maintained in the reservoir during action. An overflow N communicates also with the top of the reservoir and is conducted back, preferably to the supply.

Let it be supposed that the pipe O is in communication with the explosion-chamber of a gas-en gine, the outward movement of whose piston will tend to produce a vacuum in said pipe, thus drawing valve D from its 95 seat and simultaneously unseating the valve C. The gasoline feeds down around the point of the needle-valve, and the supply of air is drawn in through the apertures E. The air and gasoline mix as they iiow down over the Ioo valve D into the chamber F', and when the partial vacuum in the pipe is destroyed the spring F returns the valves D and G to their respective seats, closing the gasoline-port. These aetuations of the valve are preferably regular and each aetuation of equal duration, thus supplying predetermined quantities of gasoline and air and in definite proportions, While the quantity of the gas produced by the ad mixture of the gasoline and air and supplied through passage O may be regulated either manually or automatically by the regulatingvalve G. Thus if it be desired to furnish explosive charges in very rapid successionas, for example, with a high-speed enginethe regulating-valve G will be set so as to supply the proper quantity of the gas. If it be desired to run slower, the same quality of the explosive mixture will be furnished, but in less quantity.

I claiml. A generator for gasoline gas, comprising in Combination a reservoir having a port or passage, a valve for regulating the quantity ot' gasoline passing to said port, a mixingehaniber having an air-inlet and an outlet, a valve normally elosin g said outlet and a valve* stem having a prolongation adapted to close the port of the reservoir simultaneous with the closing of the outlet, substantially as described.

2. A generator for gasoline gas, comprising in combination a reservoir having a port or passage in its bottom, an inlet-valve for controlling the entrance to said port or passage, a mixingehamber and an air-eha1nber between the mixing-chamber and the reservoir, a spring-sustained valve normally elosin g the inlet to the mixing-chamber, said valve having its stem prolonged and adapted to close the liquid port or passage, a delivery pipe or passage leading from the mixing-chamber and a valve interposed in said pipe or passage and adapted by its movement to' regulate the quantity of gas delivered through the outlet, substantially as described.
